invention.

There is illustrated a portion ofa building 10, which-as in Figure l-maybel of brick 11 laid in horizontal lcourses with mortar joints12therebetween. The flashing com-v prises the anchor or upper member 14,and a swinging member V15, both formed of sheet metaly such asgalvanized iron or nonferrous metal. The anchor member 14 has a broadflange 15 laid in the mortar between two brick courses as the structure1'0 iserected, although it may of: course be inserted afterward bygouging out a suitable channel inthe joint, introducing freshly mixedmortar, and in'- serting the flange as required. The iange 16 comprisesa. major top portionof the anchor member the 'outer part 16 of which isinclined downwardly at a slight angle suiicient toreadily shed water anddrain the same away from the wall surface thereadjacent. At its outeredge the material of the anchor 'member is. bent downwardly at rightangles f forming an outer wall 17 thence inwardly at right anglesforming a bottom flange 18, and thence upwardly and outwardly at anangle of about 95 degrees or more,`forming a heel 19 at the bend, and aterminal upwardly inclined -lange 19, the lines of the last three bendsbeing equi-distant from each other, al,- t-hough this may not beessential. The upturned portion 19 stops short of the outer top part 16a distance, beingof much less extent Figure 5 illustrates a modified useofthe PATENT OFFICE from the bend than the distance between the requiredor desired. Its lower part 2O extends inwardly at an angle to the wallwhile its upper part 21 may extend approximately parallel to the wall.With the ma] or or lower portion hanging pendant against the wall, theupper edge aortion extends upwardly between the flange 19 and the wallof the building at 22, then extends at right angles outwardly o-ver theflange 19 a distance as at 22. Thence it is continued at 23 downwardlyat an angle of about degrees in spaced relation to the wall 17 of theupper member, forming ay terminal sealing flange 23 which is of greateraltitude than the flange19 so that it rests directly upon the bottomflange 18.

The top flange part 22 of the bottom member 15 is of a widthapproximately the same as that of the bottom flange 18 and the altitudeof the flange 19 is considerably less. By this, when the lower piece 15is swung outwardly and upwardly the part 22 becomes engaged between theheel 19 and the wall, the part 22 extending a distance below the heel 19and is thereby pressed against the face of the wall so as to support themajor portion of the member 15 in outwardly extending position as inFigure 1. Likewise, when the member 15 is lowered, the heel 19 pressesinwardly against the lower member 15, causing the extremity of the lowermember to lie snugly against the wall. lhen the movable member isshifted from one position to the other, the upper member 14 is slightlysprung from initial position on the wall until the swinging member 15 ismoved into such position that a flat part thereof may be confinedbetween the heel 19 and the wall, when the heel 19 springs back toinitial position.

When the roof has been laid and the lower flashing piece 15 is moveddownwardly, the pressure of the heel 19 against the part below theanchor' member 14 will be sufficient to hold the extreme lower edge ofthe lower flashing piece 14 against the upturned parts of roofing, sothat it will not be disturbed by winds or displaced by rodents. But ifso desired a simple wedge device 40 may be inserted over the member 15so as to extend between the heel 19 and the lower member 15, whereby thelatter is pressed with greater force against the wall, especially at thelower part.

The functioning of the device without the wedge has the advantage thatthe parts are held securely enough to preserve them against loosemovement and to prevent rattle and noise by winds or building vibrationsof ordinary kinds. The last named features are quite material inassuring long life and service of the flashing.

In building the anchor member into a brick wall, the wall is constructedin the usual way `to a height slightly above that to which it risdesired to have the flashing extend. A complete course of bricks beinglaid, a thin layer of mortar is applied on top of such last course,after which the flange 16 of my anchor member is laid upon the mortar,while the heel 19 is set as close as practicable to the outer surface ofthe wall. this time the member 15 is preferably in lowered position, apropA or -other means is then employed to hold the heel 19 snuglyagainst the wall while the mortar sets. It

may be found desirable to crimp or othervwise distort the edge of theflange 16 1n the wall so that it may not readily pull out of place. Itis not essential that the prop or other means be employed to hold theheel 19 forcibly against the wall while the device is being set in thewall, but the lower part of the member 15 may be simply laid lightlyagainst' the wall. Then when the'roof is applied and brought up besidethe wall to be coveredby the flashing, the thickness of the roofmaterial will hold the flashing member 15 still further outward andresult in pressure by the heel 19 thereagainstfasY indicated.

In setting the flashing in a concrete wall, the planks of the form maybe separated at the point where the flashing is to go, sufficiently topermit the outer flange and the bottom flange 18 to fit snugly betweenthem, while the flange 16 projects into the form. The flashing may besecured temporarily to the form by some approved means if desired.

The corner fittings may be made in accordance with approved practiceswhich will be readily understoodiby cornice workers and roofers. I havefound it practicable to join two short lengths of the anchor from twosides of a wall, as a right angle fitting which may be set in place as aunit. But for the lower members coordinated therewith, I may simply cutoff a portion of the flange 22-23, leaving only the lower body portionof the members 15 where they underlie the right angle fitting. Theprojecting ends may then be bent around the corner of the wall inoverlapped relation, and tack soldered or held by wedges at theupperparts as before mentioned.

It will be noted that while the aggregate vertical measurement of theparts 19 and 23 is greater than the distance from the part 1G to theflange 18, still when the two parts have been formed and are to bebrought together, this may be done by simply presenting the part 22against the under side of the part 18 and then pressing the flange 23outward and against the inclined flange 19, the two yielding to andsliding on each other until the top part of the member 16 is properlyentered in the top member 14. I

It is also possible toi keep the parts separate while the upper oranchor member is built into the wall, and then-after the mortar hassetthe member 15 with its major part horizontal as 'shown in Figure 1,may

be presented beneath the flange 18, and the flange 23 pressed upwardbehind `the heel 19 until the one snaps over the other and ythe heelsprings outward against the part 22 as shown in Figure l.4

lhen made in galvanized iron (which is largely used for fiashings) thespring action of the heel 19 is quite positive and not liable toimpairment, on account of the inherent resilience of the material ascustomarily manufactured, notwithstanding that the material is readilybent to the forms desired. In soft copper the action would still befound, though more care is required in handling the material to avoiddeformation.

I claim:

l. A two piece flashing comprising an upper member having a body adaptedto be set in a wall and having a downturned and inturned outer edge theextremity7 of which is presented inwardly as a presser heel tending toengage a wall in which the member is set; and a lower member swinginglymounted on the lirstthe swinging connection consisting of an outwardlyand downwardly turned edge portion having a flat part arranged to beengaged by said heel and pressed against a supporting wall when thelower member is swung upwardly to inoperative position, the downturnedpart of the lower member arranged to rest upon the inturned part of theupper member and hold a substantial part of the lower part of the memberextending above the heel when the parts are in operative position,whereby the bottom member is then pressed against the wallby said heelas described.

2. A flashing of the character described comprising an anchor memberhaving a flange portion adapted to be set in a wall or the like, itsouter part being bent downwardly, then inwardly, and its terminal edgebeing arranged as a presser heel; and a-swinging member having an upperedge portion pressed4 upon b-y said heel and extended above and bentoutward at a sharp angle above the heel, its terminal edge being shapedfor retaining engagement with the heel.

3. A flashing of the character described comprising an anchor memberhaving a body portion adapted to be set in a wall or other' structuralelement its outer part being bent downward spaced outward from the planeof the wall face, then bent inward spaced below the body and then bentupwardly on a line at said plane to form a presser heel, the eX- tremityof the last named upwardly bent portion stopping short of the firstnamed body portion a distance; and a swinging member adapted to lieagainst a wall having an upper edge portion bent outwardly at a sharpangle to form a flat extending over the last named part of the anchormember, and then being bent downwardly at a sharp angle spaced from thefirst named downturned part of the anchor member and extended a distancegreater than the space between the body and upturned part of the anchor.

4. In a flashing of the character described,

an upper anchor member having downturned f and inturned outer edgeportions, and a lower swinging member having outturned and downturnedupper edge portions set within said outer portions. of the anchor memberas a pivot, said swinging member having angularly disposed Hat partsadjacent the pivot positioned to lie alternately against an engaged wallby pivotal adjustment, said outer portions of the anchor member havingan eX- treme part positioned to yieldingly interlock at respectivepositions with the flat parts, whereby to oppose yieldingly relativepivotal movement of the anchor and swinging members at operative andinoperative positions.

5. rIlhe structure of claim 4 in which the kanchor member has anupturned outwardly inclined eXtreme edge portion, the downturned parto-f the swinging member is inclined inwardly and the aggregate verticaldimensions of the upturned part of the anchor member and the downturnedpart of the swinging member exceed the vertical distance between thebody of the anchor member and the inturned part thereof, whereby kwhenpressed laterally together the eXtreme edge portions yieldingly coengageand slide upon and past each other, and prevent reverse separatingmovement.

In testimony whereof I aiiix my signature.
